5/16 CUTTER CLAMSHELL(3PACK) RB7A | eBaydiy Tools

Rotabroach® Annular tools cut clean, burr-free, round holes fast, unlike twist drills that push or hole saws that tear thru materials
Multiple cutting teeth are precision ground instead of stamped like hole saws, give long tool life
Rotabroach® Cutters are for precision hole making in sheet metal, frame materials, and plate stock up to ½\” thick, whether Mild Steel, Stainless Steel, or Aluminum
For body shops and frame straighteners, custom building and detailing, after market installations, rust proofers and undercoaters – wherever fast, rugged, and superior quality holes are required – Rotabroach Cutters are the single answer
Patented tooth geometry also prevents chip clogging when cutting steel, sheet metal, or plastics
